IMPROVEMENT IN REVOLVING :FIRE/XMMS.

Specification forming part of Letters Patent No. 62,20, dated April 20,1875; application filed February 4, 1875.

To all whom it may concern Be it known that I, ROLLIN VVHI'LE, ofLowell, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Revolving Fire- Arms;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsand letters of reference marked thereon, making a part of thisspecification.

The nature of my invention relates to an improvement in fire-arms; andit consists in the arrangement and combination of parts, which will bemore fully described hereafter.

Figure l is a side view ot' my improvement. Fig. 2 is a front view ofthe recoil-shield, the multiple cartridge-extractor, and abutment. Figs.3, 4, 5, and 6 are front views of the cartridge-extractor, representingthe different forms and positions ot' the same. Fig. 7 is a view of thecentral cartridge-extractor. Fig. S is a front view of the externalcartridge-extractor. Fig. 9 is a longitudinal section ot' thecartridge-ex tractors. Fig. 10 is a longitudinal section of thecartridge-extractor, ratchet, and base-pin. Fig. ll is a longitudinalsection of my improvement, showing cartridge in the upper chamber, withflange behind both central and external extractor, and cartridge inlower chamber free from both extractors. Fig. l2 is a side elevation,showing the catch adapted as a lever for starting the cylinder. Fig. 13is an enlarged perspective view of the central cartridge extractor.

A represents the lock-frame; B, the barrel; C, the cylinder; D, thecentral pin on which the cylinder revolves. This pin is loosely fittedin the cylinder, so that it may turn freely thereon, and this pin isconnected to the barrel by the toggle-joint E and F. The barrel B ishinged to the lock-frame, and as it swings froina line ofthe chambersthe togglejoint will open until the barF comes in contact with ashoulder in the barrel, and as the barrel swings farther to about rightangles it operates as a lever, and forces the cylinder from the breechand from the cartridge-extractors R and U, and by this means draws thecartridge from the chambers. By means of the toggle-joint the barrel :isattached to the cylinder, and by swinging up the barrel thecartridge-shells will be exa locking-bolt.

tracted, and the cylinder can be removed from the frame and recharged,and returned to its place for firing. ,As the barrel swings back to theline of-'the chamber the lever H locks the barrel to the fram e. Grepresents a shoulder on, or a notch in, the cylinder, for a hook, stud,or lever to press against and force the cylinder from the breech orcartririge-extractor. M is a hook fastened to the barrel by a pivot, andas the barrel swings up this hook comes against the shoulder Gr, andforces the cylinder from the recoil-shield or the cartridge-extractor.As the barrel swings up, the hook turns on its pivot, the notch on thehook is brought in line wit-h the spring L, and it enters the recess Nor O in the hook, and holds it free from contact with the cylinder. Thisspring also acts on a cam, Q, on the back ofthe hook M, to hold itagainst the notch or shoulder on the cylinder when desired. The notch onthe hook is made hooking, and the shoulder on the cylinder tocorrespond. By this form the hook `will not slip olf when force isapplied to the lever or barrel. H represents the lever, pivoted to thelock-frame, with a projection, I, and forms By swinging down the lever Hthe lockingbolt K slides oft' of the shoulder on the projection of thebarrel, and leaves the barrel free to swing up, and liberating thecylinder, while the projection I presses against the shoulder G, andforces the cylinder from the cartridgeextractor, and by this means drawsout the cartridge shells. R represents an annular abutment andpartially-rotating c trtridge-eXtr-actor. In Fig. 2 the line of theabutment It is opposite to the flange on the central cartridge-extractorU. This annular abutment is attached to the lock-frame, and as thecylinder is forced from it, and the flange or projection, the cartridgeshells will be drawn completely' out ofthe chambers before the frontends of the shells can tip enough to let the rim of the shells slide outof the abutment and off from thc llange.

The space between the abutment and the llange is of less diameter thanthe rim on the cartridge. This space should be slightly larger than thediameter of the shell and onehalf of the rim, and then it will beimpossible for the rim of the cartridge to pass out between the abutmentand the flange until the shell is out of the chambers. On one side ofthis abutment, in Fig.2, is represented a projection or iiange, T, andopposite to it an abutment, for the same purpose as above described. InFig. 2 the central and external abutments are opposite to each other atV, and a cartridge in the cylinder. When it is put into the lock-frameand taken out, the rim will slide in and out between the abutments, andwill not be withdrawn upon moving the cylinder; but by turning theabutment R it will bring the shoulder S against the lock-frame, and theflange or projection will come opposite to the abutment V, and thecartridge will be extracted by forcing the cylinder from the breech orcartridge-extractor. These changes are more clearly represented in Figs.3 and 4. In Fig. 3 the projections or flanges and the abutments orrecesses are opposite to each other, and a cylinder charged can be pntinto its place or taken off without extracting the shell, as the rim ofthe shell will be free to slide in and out between the abutments, but byturning the cartridge-extractor R as represented in Fig. 4, or turningthe cylinder to its locking-bolt, ready to lire the pistol, and thecylinder is then forced off from the cartridge-extractor, the shellswill all be thrown out of the chambers. The extractors, as representedin Figs. 7 and 8, can be used separately, or only one of them, andaccomplish the same purpose in starting the shell from the chamber; butneither of them, separately, will be sure to draw all thecartridgeshells completely out of the chambers unless the cylinder isjerked out from the frame or moved with great velocity. Fig. 5 is a viewof the external cartridge-extractor with a continuous ange, and acentral abutment without flange. Fig. 6 represents an external abutmentand a continuous flange on the central extractor, with thecartridge-ejector and abutments, as represented in Figs. 5 and 6. rlhecylinder is charged while in the lock-frame, and through an opening inthe vrecoil-shield. The central cartridge-extractor U is attached to thebreech or recoil-shield, and has a projection or flange on a section ofit, and on this liange is a cam. The other section V forms an abutmentfor the rims of the cartridges. The projection or flange and theabutment are between the chamberand the central portion of the rear endof the cylinder. The projection or ange comes close to the chamber, andin front of a section of the rim of the cartridges in the cylinder. Byrevolving the cylinder the cam on the flange will start each cartridgeseparate] y, or, by forcing the cylinder from the cam on thecartridge-extractor, the cartridges will be started successively fromthe chambers. Figs. 9 and l() are central longitudinal sections otcartridge-extractors R and U, abutment V, loose pin Y, projection orcouplingpin Z, and ratchet X. In some cases it is dcsirable to removethe cylinder from the pistolframe while charging it, and in other casesit is not; or it may be attached to the barrel, and therefore I haverepresented various forms and means ot' carrying out my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination, substantially as described, of a revolving cylinder,an extractor for withdrawing cartridges therefrom, and a lateralabutment, for the purposes set forth.

2. In a tire-arm, a revolving cylinder, a central extractor or abutment,and an annular movable abutment or extractor, when combined foroperation substantially as described.

3. The combination. in a revolving tire-arm, of a frame havingprojecting therefrom a hollow ixed or non-rotating centrally-arrangedcartridge-extractor, a revolving chambered cylinder, and a lever fordrawing or starting the cylinder away from the recoilshield andextractor, substantially as shown and described.

4. In a revolving iire arm, having a non-rotating centralcartridge-extractor, the combination therewith of a cam for successivelystarting the cartridge as the cylinder revolves, substantially as setforth.

5. The combination,in a fire-arm, of a revolving cylinder, atoggle-joint, and a hinged barrel, adapted to withdraw the cylinderdirectly away from an extractor xed to the recoilshield, substantiallyas set forth.

6. ln combination with a revolving and sliding cylinder provided withshoulders or notches, a hook and lever or swinging barrel for startingthe cylinder, substantially as specified.

7. In combination with a revolving cylinder and hinged or swingingbarrel, the catch-lever H, adapted to operate as a means of starting thecylinder, the construction and operation being substantially asdescribed.
